Description

Technical Field

[0001] This utility model relates to the field of product palletizing technology, specifically to a timber transfer system and a sleeper palletizing system. Background Technology

[0002] After production, some products need to be stacked for easy storage and transportation. During stacking, wooden blocks are often placed between product layers to minimize damage during stacking and transportation. For example, prefabricated components (such as railway sleepers and small prefabricated parts) are highly susceptible to damage under heavy loads and collisions, which can affect product quality and yield.

[0003] With technological advancements and production needs, cost reduction and efficiency improvement are the relentless pursuits of manufacturing enterprises. The production of some prefabricated components has already achieved a high degree of automation, and the automated handling and transfer of wooden blocks has become a key focus of current technological development. Improving the transfer efficiency and reliability of wooden blocks is crucial for the stacking of prefabricated components.

[0004] In actual production processes, because sleeper blocks are often stacked in piles with crisscrossing layers, and some blocks may deform or break after a period of use, coupled with factors such as uneven stacking and inconsistent lengths, automated transfer of sleeper blocks presents significant challenges. To address these challenges, the applicant has proposed a sleeper block transfer system and a sleeper stacking system. Utility Model Content

[0054] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also mean including the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof.

It should also be understood that additional or alternative steps may be used.

[0055] Although terms such as "first," "second," and "third" may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these technical terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as a first element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0059] In this application, "above a certain number" includes the number itself; for example, "two or more" includes two.

[0060] In this application, the descriptions of "basically perpendicular" and "basically parallel" are used to ensure that the scope of protection sought covers technical solutions that are not perpendicular or parallel due to processing errors, installation errors, etc.

[0061] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0062] The following is combined Figures 1 to 14 This invention introduces the timber transfer system 100 and the sleeper stacking system provided by this utility model.

[0063] The timber transport system 100 provided in this application is used for acquiring and transporting timber. The timber transport system 100 includes a first load-bearing structure, a second load-bearing structure, a traveling beam 21, and a timber picking and placing device. Wherein, for example... Figure 1 As shown, the first load-bearing structure includes a first load-bearing beam 1001; the second load-bearing structure includes a second load-bearing beam 1002, with the first load-bearing beam 1001 and the second load-bearing beam 1002 arranged side by side. A traveling beam 21 spans the first load-bearing beam 1001 and the second load-bearing beam 1002, and the traveling beam 21 is configured to travel along the length of the first load-bearing beam 1001 and the second load-bearing beam 1002. A timber loading and unloading device is drivenly connected to the traveling beam 21; the timber loading and unloading device is configured to be able to pick up and release timber and to move laterally and vertically relative to the traveling beam 21. In a specific implementation, such as Figure 12 , Figure 13 and Figure 14 As shown, the timber transfer system 100 also includes a timber placement area 1004 and a product transfer stop area 1005. The timber placement area 1004 is located below the running trajectory of the timber picking and placing device; the product transfer stop area 1005 is located below the running trajectory of the timber picking and placing device.

[0064] It should be explained that, in this application, "the timber picking and placing device can move laterally relative to the traveling beam 21" means that the timber picking and placing device can move along the span direction of the traveling beam 21. In this application, "the timber picking and placing device can move vertically relative to the traveling beam 21" means that the timber picking and placing device can move along the height direction of the traveling beam 21, that is, the timber picking and placing device can move along the span direction perpendicular to the traveling beam 21.

[0065] In practical implementation, both the traveling beam 21 and the timber loading / unloading device are further controlled by the control unit. Specifically, the timber transport system 100 also includes an information acquisition unit 61, an information processing unit, and a control unit. The information acquisition unit 61 is configured to at least acquire the location information of the timber to be acquired; or the information acquisition unit 61 is configured to at least acquire the location information of the timber to be acquired and the location information where the timber is to be placed. The information processing unit is signal-connected to the information acquisition unit 61 and is configured to collect and process the information acquired by the information acquisition unit 61, encoding it into control commands. The control unit is signal-connected to the information processing unit, and the control unit is capable of receiving and executing the control commands encoded by the information processing unit to control the timber transport system 100.

[0066] In practical implementation, the information acquisition unit 61 can be selectively configured as a 3D camera. Furthermore, the information acquired by the information acquisition unit 61 can be selectively set according to the actual needs of transporting the wooden blocks. Specifically, for example... Figure 1 , Figure 12 , Figure 13 and Figure 14 As shown, the 3D camera is mounted on the traveling beam 21 via the mounting bracket 62.

[0067] It should be noted that the terms "first load-bearing structure" and "second load-bearing structure" in this application are not specifically limited, and can be any structure that meets the walking and load-bearing requirements of the walking beam 21. Specifically, as shown below... Figure 1 As shown, the first load-bearing structure includes a first load-bearing beam 1001 and two supporting columns 1003, with the first load-bearing beam 1001 spanning the two spaced-apart supporting columns 1003. The second load-bearing structure includes a second load-bearing beam 1002 and two supporting columns 1003, with the second load-bearing beam 1002 spanning the two spaced-apart supporting columns 1003. In a specific implementation, the timber stack transfer system 100 is configured such that the product transfer equipment can transfer products to a position below the running track of the timber stacking and placing device. This application, by including the first load-bearing structure with the first load-bearing beam 1001 and supporting columns 1003, and the second load-bearing structure with the second load-bearing beam 1002 and supporting columns 1003, facilitates the movement of timber stacks and product transfer equipment between the two supporting columns and below the running track of the timber stacking and placing device.

[0068] It should also be noted that there is no specific limitation on the number of supporting columns 1003 included in the first and second load-bearing structures. In specific implementations, the number of supporting columns 1003 included in the first and second load-bearing structures can be selectively set to three, four, or five, depending on actual needs. To further improve the stability of the first and second load-bearing structures, they can also be selectively connected by a crossbeam.

[0069] The term "traveling beam" in this application is not specifically limited; it can be any structure that meets the installation requirements of the timber loading and unloading device and is capable of moving along the first bearing beam 1001 and the second bearing beam 1002. In specific implementations, such as... Figure 1 As shown, the traveling beam 21 spans the first bearing beam 1001 and the second bearing beam 1002, and both the first bearing beam 1001 and the second bearing beam 1002 are provided with traveling guide rails 1006 extending along the length direction of the bearing beam. At both ends of the traveling beam 21, there are traveling wheels that are adapted to the traveling guide rails 1006, so that the traveling beam 21 can move along the bearing beam via the traveling wheels.

[0070] In this application, the so-called "wooden pad picking and placing device" is a device used to pick up and release wooden pads. In specific implementation, the wooden pad picking and placing device is positioned above the wooden pad placement area 1004 and the product transfer stop area 1005, and is controlled by a control unit. In specific operation, the wooden pad picking and placing device picks up wooden pads from the wooden pad placement area 1004, and moves to above the product transfer stop area 1005 under the drive of the traveling beam 21, and further places the picked-up wooden pads on top of the products in the product transfer stop area 1005 to complete one wooden pad transfer process.

[0071] This application includes a first supporting beam 1001 and a second supporting beam 1002 in the timber transport system 100, with a traveling beam 21 spanning the first and second supporting beams 1001 and 1002. The timber picking and placing device is connected to the traveling beam 21, enabling the traveling beam 21 to drive the timber picking and placing device along the first and second supporting beams 1001 and 1002, thus allowing the timber transport system 100 to transport timber within the working space. Secondly, by connecting the timber picking and placing device to the traveling beam 21 and enabling the device to move laterally and longitudinally relative to the traveling beam 21, this application effectively increases the working space of the timber picking and placing device, better meeting the timber transport requirements. Thirdly, by placing both the timber picking and placing device and the product transport stop area 1005 below the running trajectory of the timber picking and placing device, the timber picking and placing device can move with the traveling beam 21 and move laterally and longitudinally relative to the traveling beam 21, thus meeting the needs of timber transport.

[0072] In specific implementation, such as Figure 12 , Figure 13 and Figure 14 As shown, travel guide rails 1006 are provided on both the first bearing beam 1001 and the second bearing beam 1002, and the travel guide rails 1006 extend along the length direction of the first bearing beam 1001 and the second bearing beam 1002. For example... Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, at both ends of the walking beam 21, there are walking wheels that are adapted to the walking guide rail 1006 on the walking beam 21.

In specific implementation, it is preferable that the lifting arm 201 is a long strip structure processed from profiles (such as square steel pipes, I-beams, etc.). By including the lifting arm 201 in the log transfer system 100, this application allows the position of the log picking and placing unit 1 to be adjusted according to the location of the log to be obtained and the location where the log is to be placed, so as to meet the position adjustment requirements of the log picking and placing unit 1 when the height of the log stack changes.

In a specific implementation, the second drive motor 31 is electrically connected to and controlled by the control unit.

[0084] This application further includes a second drive motor 31, a fourth gear 32, and a fourth rack 33 in the timber transport system 100. By connecting the first mounting connection structure 24 to the fourth rack 33 mounted on the traveling beam 21 via the fourth gear 32, the first mounting connection structure 24 can drive the timber picking and placing unit 1 to adjust its position along the length of the traveling beam 21 by using the meshing transmission of the gear and rack. This can effectively ensure the positional accuracy of the timber picking and placing unit 1 in the length of the traveling beam 21.

[0085] In addition, this application can further adjust the position of the wooden block picking and placing unit 1 by controlling the first drive motor 22 and the second drive motor 31, thereby realizing the automated control of the position adjustment of the wooden block picking and placing unit 1.

[0087] In this application, the slewing unit 202 is not specifically limited, and it can be a unit that enables the wooden block picking and placing unit 1 to rotate relative to the lifting arm 201.

[0088] It should be explained that the phrase "the rotation surface of the rotary unit 202 is substantially perpendicular to the length direction of the lifting arm 201" in this application is intended to cover solutions where the rotation surface of the rotary unit 202 is not perpendicular to the length direction of the lifting arm 201 due to processing errors, installation errors, or other reasons.

[0089] This application includes a rotary unit 202 in the pad placement device, which enables the pad placement unit 1 to rotate, giving it greater freedom and a larger working space. This allows the pad placement unit 1 to adjust its position according to the location of the pad to be acquired. Consequently, it can effectively meet the position adjustment requirements under conditions such as pad deformation, wear, uneven pad stacking, and pads of varying lengths, thereby effectively improving the reliability of the pad transfer equipment in acquiring pads.

[0090] As some preferred embodiments of this application, the lifting arm 201 includes a lifting arm body 2011 and a second mounting connection structure 2012, the second mounting connection structure 2012 being located at one end of the lifting arm body 2011. Specifically, as... Figure 6 and Figure 8 As shown, the slewing unit 202 includes a slewing drive motor 2021, a fifth gear, and a toothed slewing bearing 2023. The slewing drive motor 2021 is mounted on the second mounting connection structure 2012. The fifth gear is driveably connected to the power output end of the slewing drive motor 2021, and the fifth gear is meshed with the toothed slewing bearing 2023. The pad wood picking and placing unit 1 is connected to the toothed slewing bearing 2023.

[0091] This application includes a rotary unit 202 comprising a rotary drive motor 2021, a fifth gear, and a toothed slewing bearing 2023. Both the rotary drive motor 2021 and the toothed slewing bearing 2023 are mounted on the second mounting connection structure 2012 included in the lifting arm 201. Furthermore, the rotary drive motor 2021 is driven by the fifth gear meshing with the toothed slewing bearing 2023. The timber loading / unloading unit 1 is connected to the toothed slewing bearing 2023. Driven by the rotary drive motor 2021, the timber loading / unloading unit 1 can rotate with the toothed slewing bearing 2023, facilitating automated control of the timber loading / unloading unit 1's position adjustment. Additionally, using gear meshing to adjust the position of the timber loading / unloading unit 1 effectively ensures its positional accuracy, facilitating automated control of timber loading / unloading.

[0092] It should be noted that the second mounting connection structure 2012 is not specifically limited; it can be any structure that meets the mounting requirements of the rotary drive motor 2021 and the toothed slewing bearing 2023. Specifically, as follows... Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the second mounting connection structure 2012 is a mounting plate. The mounting plate is fixed to the downward-facing end of the lifting arm body 2011.

[0093] It should also be noted that the "toothed slewing bearing 2023" in this application can be selectively set as an external toothed slewing bearing (e.g., Figure 6 or Figure 8 (as shown) or configured as an internal gear slewing bearing (not shown in the figure).

[0094] It should be noted that the lifting arm body 2011 in this application is not specifically limited, and it can be any structure that can meet the needs of adjusting the vertical position of the log picking and placing device during the log transfer process of the log transfer system 100. In specific implementation, it is preferable that the lifting arm body 2011 is a long strip structure processed from profiles. By including the lifting arm 201 in the log picking and placing device, this application allows the position of the log picking and placing unit 1 to be adjusted according to the position of the log to be picked up and the position of the log to be placed, so as to meet the position adjustment requirements of the log picking and placing unit 1 when the height of the log stack changes.

[0095] As some preferred embodiments of this application, such as Figure 8 and Figure 9As shown, the wood padding device includes a mounting base 101, a first push-pull assembly 102, and two wood padding units 1. The mounting base 101 is connected to a toothed slewing bearing 2023. The two wood padding units 1 are arranged side by side, and each of the two wood padding units 1 is connected to the mounting base 101 via at least one first push-pull assembly 102. The pushing and pulling direction of the first push-pull assembly 102 is parallel or substantially parallel to the length direction of the lifting arm 201.

[0096] The structure of the mounting base 101 in this application is not specifically limited; it can be any structure that meets the installation requirements of the two wooden support units 1. In specific implementation, such as... Figure 10 The mounting base 101 shown includes a mounting flange 1011 and a mounting platform 1012. The mounting platform 1012 is fixed at the center of one side of the mounting flange 1011. The mounting platform 1012 is generally square and is used to connect the pad placement unit 1. The mounting flange 1011 is used to connect the mounting base 101 to a set position.

[0097] Furthermore, the first push-pull assembly 102 in this application is not specifically limited; it can be any push-pull assembly capable of applying a push-pull force to the wooden block picking and placing unit 1 and meeting the requirements for wooden block transportation. In specific implementations, the first push-pull assembly 102 can be selectively configured as a telescopic cylinder (which can be a pneumatic or hydraulic telescopic cylinder), a gear and rack linear module, a lead screw and slider linear module, a synchronous belt linear module, etc. For example... Figure 8 and Figure 9 As shown, the first push-pull assembly 102 is a pneumatic telescopic cylinder. Further, the first push-pull assembly 102 is connected to a pressurized gas source via a control valve, and the control valve is connected to and controlled by a control unit. Alternatively, the first push-pull assembly 102 can be optionally a hydraulic telescopic cylinder.

[0098] It should be explained that the phrase "the pushing and pulling direction of the first push-pull assembly 102 is substantially parallel to the length direction of the lifting arm 201" in this application is intended to cover solutions where the pushing and pulling direction of the first push-pull assembly 102 is not parallel to the length direction of the lifting arm 201 due to processing errors, installation errors, or other reasons.

[0099] This application includes a mounting base 101 in the log-picking and placing device, thereby enabling the device to meet the installation requirements of multiple log-picking and placing units 1. Secondly, by including two log-picking and placing units 1 side-by-side, the device can transport two logs at a time, effectively improving log transport efficiency and consequently, product stacking efficiency. Thirdly, by including two units 1, the device can selectively transport one or two logs at a time according to actual log transport needs, better meeting these requirements. Fourthly, by connecting the log-picking and placing unit 1 to the mounting base 101 via a first push-pull assembly 102, the position of the log to be placed can be adjusted during placement to avoid collisions or interference from another log-picking and placing unit 1.

[0100] As some preferred embodiments of this application, such as Figure 11 As shown, the pad placement and removal unit 1 includes a mounting beam 11, a first clamping member 12, a second clamping member 13, a second push-pull assembly 14, and a third push-pull assembly 15. Specifically, the first clamping member 12 is movably connected to the first end of the mounting beam 11, and has a first clamping portion 121. The first clamping member 12 is connected to the push-pull end of the second push-pull assembly 14, with the push-pull end of the second push-pull assembly 14 facing the first end of the mounting beam 11. The second clamping member 13 is movably connected to the second end of the mounting beam 11, and has a second clamping portion 131. The first clamping portion 121 and the second clamping portion 131 are opposite each other. The second clamping member 13 is connected to the push-pull end of the third push-pull assembly 15, with the push-pull end of the third push-pull assembly 15 facing the second end of the mounting beam 11.

[0101] This application includes a mounting beam 11, a first clamping member 12, and a second clamping member 13 in the pad placement and retrieval unit 1, enabling the acquisition and transfer of pads through clamping, thereby achieving a more reliable pad placement and transfer process. Furthermore, by connecting the first clamping member 12 to the first end of the mounting beam 11 and the second clamping member 13 to the second end of the mounting beam 11, with the first clamping part 121 and the second clamping part 131 facing each other, the pads can be clamped along their length, effectively avoiding interference and influence from adjacent pads, thus improving the reliability of the pad placement and retrieval device.

[0102] In specific implementation, such as Figure 11As shown, the second push-pull assembly 14 is mounted on the mounting beam 11, and the push-pull end of the second push-pull assembly 14 is connected to the first clamping member 12. The second push-pull assembly 14 is controlled by the control unit so that the first clamping member 12 can move towards or away from the second clamping part 131 under the action of the second push-pull assembly 14. At the same time, the third push-pull assembly 15 is mounted on the mounting beam 11, and the push-pull end of the third push-pull assembly 15 is connected to the second clamping member 13. The third push-pull assembly 15 is controlled by the control unit so that the second clamping member 13 can move towards or away from the first clamping part 121 under the action of the third push-pull assembly 15.

[0103] This application includes a second push-pull assembly 14 and a third push-pull assembly 15 in the wood pad picking and placing unit 1. Under the action of the second push-pull assembly 14 and the third push-pull assembly 15, the distance between the first clamping part 121 and the second clamping part 131 can be adjusted to facilitate the picking and releasing of the wood pad. In addition, the second push-pull assembly 14 and the third push-pull assembly 15 are controlled by a control unit to achieve automated control of wood pad picking and placing.

[0104] The mounting beam 11 in this application is not specifically limited and can be any beam that meets the installation and load-bearing requirements. In specific implementations, the mounting beam 11 is preferably made of profile. In specific implementations, the length of the mounting beam 11 is selectively set according to the length of the pad being picked up or placed. The minimum distance between the first clamping part 121 and the second clamping part 131 is less than the length of the pad, and the maximum distance between the first clamping part 121 and the second clamping part 131 is greater than the length of the pad; furthermore, the pad picking and placing unit 1 clamps the pad along the length direction of the pad.

[0105] The structure of the first clamping member 12 in this application is not specifically limited; it can be any structure that includes a first clamping portion 121 and is able to be opposite to the second clamping portion 131 to meet the requirements for clamping the dunnage. Similarly, the structure of the second clamping member 13 in this application is not specifically limited; it can be any structure that includes a second clamping portion 131 and is able to be opposite to the first clamping portion 121 to meet the requirements for clamping the dunnage.

[0106] Specifically, for example Figure 11 As shown, the first clamping member 12 includes a first segment and a second segment, which are connected and form an L-shape. The first segment is connected to the push-pull end of the second push-pull assembly 14, and the first clamping part 121 is located in the second segment and faces the clamping part of the second clamping member 13. Similarly, the second clamping member 13 includes a third segment and a fourth segment, which are connected and form an L-shape. The third segment is connected to the push-pull end of the third push-pull assembly 15, and the second clamping part 131 is located in the fourth segment and faces the clamping part of the first clamping member 12.

[0107] To better clamp the wooden block, in specific implementations, it is preferable that both the first clamping part 121 and the second clamping part 131 have uneven clamping surfaces, specifically as follows: Figure 11 As shown, both the first clamping part 121 and the second clamping part 131 are provided with teeth, and both the first clamping part 121 and the second clamping part 131 are provided with two toothed areas to improve the local clamping force of the first clamping part 121 and the second clamping part 131, so as to more reliably clamp the transported pad.

[0108] In practical implementation, the first clamping member 12 and the second clamping member 13 are arranged at both ends of the mounting beam 11 along the length direction of the mounting beam 11, so that the pad wood picking and placing unit 1 can pick up the pad wood from both ends of the pad wood. This application connects the first clamping member 12 to the first end of the mounting beam 11 and the second clamping member 13 to the second end of the mounting beam 11, and makes the first clamping part 121 and the second clamping part 131 opposite to each other, thereby enabling the pad wood to be picked up along the length direction of the pad wood. This effectively avoids interference and influence caused by adjacent pad wood on the pad wood picking and placing, thereby improving the reliability of the pad wood picking and placing device.

[0109] It should also be noted that the second push-pull assembly 14 in this application is not specifically limited, and it can be any push-pull assembly capable of applying a push-pull force to the first clamping member 12 and meeting the requirements for clamping the pad. In specific implementations, the second push-pull assembly 14 can be selectively made into a telescopic cylinder (specifically, a pneumatic telescopic cylinder or a hydraulic telescopic cylinder), a gear and rack linear module, a lead screw and slider linear module, a synchronous belt linear module, etc.

[0110] As a preferred embodiment of the foregoing implementation, the second push-pull assembly 14 is a first telescopic cylinder, such as... Figure 11 As shown, the cylinder body of the first telescopic cylinder is connected to the first end of the mounting beam 11, and the telescopic end of the first telescopic cylinder faces the first end side of the mounting beam 11. The telescopic end of the first telescopic cylinder is connected to the first clamping member 12. The pad placement unit 1 also includes a first slide rail 16 and a first slider 17 slidably adapted to the first slide rail 16. The first slide rail 16 is fixed at the first end of the mounting beam 11 and extends along the length of the mounting beam 11. The first slider 17 is fixedly connected to the first clamping member 12, and the first clamping member 12 is slidably connected to the first slide rail 16 via the first slider 17. The first clamping member 12 is used to clamp the first end of the pad. In a specific implementation, the first telescopic cylinder is connected to the medium source pipeline via a control valve. The control valve is electrically connected to the control unit and controlled by the control unit.

[0111] In practical implementation, when the first telescopic cylinder is a pneumatic telescopic cylinder, it is connected to a gas source (air tank or air compressor, etc.) via a control valve, and the control valve is further electrically connected to and controlled by the control unit. When the first telescopic cylinder is a hydraulic telescopic cylinder, it is connected to a hydraulic oil tank via a control valve and a hydraulic pump, and the control valve is further electrically connected to and controlled by the control unit.

[0112] It should be noted that the third push-pull assembly 15 in this application is not specifically limited, and it can be any push-pull assembly that satisfies the requirement of applying a push-pull force to the second clamping member 13 and meeting the clamping requirements of the pad. In specific implementations, the third push-pull assembly 15 can be selectively made into a telescopic cylinder (specifically, a pneumatic telescopic cylinder or a hydraulic telescopic cylinder), a gear and rack linear module, a lead screw and slider linear module, a synchronous belt linear module, etc.

[0113] In specific implementation, the third push-pull assembly 15 is preferably a pneumatic telescopic cylinder. Furthermore, the cylinder body of the pneumatic telescopic cylinder is mounted on the mounting beam 11, with the telescopic end of the cylinder facing the second end side of the mounting beam 11 and connected to the second clamping member 13. This application, by including the third push-pull assembly 15 in the log loading and unloading unit 1 and connecting the second clamping member 13 to the push-pull end of the third push-pull assembly 15, enables the log loading and unloading unit 1 to simultaneously activate the first clamping member 12 and the second clamping member 13, effectively improving the efficiency of log loading and unloading. In addition, it effectively alleviates or avoids the problem of uneven loading of logs during transport. Furthermore, the third push-pull assembly 15 can be controlled by a control unit to achieve automated control of log loading and unloading.

[0114] As some preferred embodiments of the foregoing implementation, the third push-pull assembly 15 may be selectively configured as a second telescopic cylinder, the cylinder body of which is connected to the second end of the mounting beam 11, and the telescopic end of which is connected to the second clamping member 13. Figure 11 As shown, the wood pad placement and removal unit 1 also includes a second slide rail 18 and a second slider 19 that is slidably adapted to the second slide rail 18. The second slide rail 18 is fixed at the second end of the mounting beam 11 and extends along the length of the mounting beam 11. The second slider 19 is fixedly connected to the second clamping member 13, and the second clamping member 13 is slidably connected to the second slide rail 18 via the second slider 19. The second clamping member 13 is used to clamp the second end of the wood pad. Furthermore, the second telescopic cylinder is connected to the medium source pipeline via a control valve. The control valve is electrically connected to the control unit and is controlled by the control unit.

[0115] This application enables the first clamping member 12 to be slidably connected to the first slide rail 16 via the first slider 17, and the second clamping member 13 to be slidably connected to the second slide rail 18 via the second slider 19, thereby enabling the first clamping member 12 and the second clamping member 13 to have better positional accuracy, which facilitates the automation of the transfer of wooden blocks, especially the automation of vision-based wooden blocks.

[0116] In practical implementation, when the second telescopic cylinder is a pneumatic telescopic cylinder, it is connected to a gas source (air tank or air compressor, etc.) via a control valve, and the control valve is further electrically connected to and controlled by the control unit. When the second telescopic cylinder is a hydraulic telescopic cylinder, it is connected to a hydraulic oil tank via a control valve and a hydraulic pump, and the control valve is further electrically connected to and controlled by the control unit.

The sleeper transfer device 200 is configured to transfer sleepers. The transfer route of the sleeper transfer device 200 passes through the product transfer stop area 1005.
